' EXTENSIBLE PICTURE FRAME.

Application filed March 6, 1926. Serial No. 92,734.

This invention relates to extensible picture frames and its main object is the provision of a frame composed of a plurality of cooperating frame sections which are adapted to be adjusted in respect of each other to providea frame whichwould fit various sizes of pictures. V Anotherobject of the invention is to provide a frame composed of four corner sections where the ends of the adjacent corner sections form the side's'of the frameand which are adjustable longitudinally for varying the length of the sides for accomodating pictures of various sizes. lVith the above general objects in View and others that will appear as the nature of the invention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated in the accoinpanying drawings and pointed out in the appended claims.

In the drawings forming a part of this application, and in which'like designating characters refer to corresponding parts throughout the several views, 7 1

i Fig. 4 is an elevational view of frame support; l V Fig. 5 is a cross-sectional view of the support taken on line 55 of Fig. it, looking downwardly 6 is a face view of a blank out of which cornersec'tions are constructed by suitably forming theblan'k; v

- Fig. 7 isa front-elevational View of one corner section and of the ends of two adjacent corner sections illustrating. the cooperation between the-corner sections of the frame;

Fig. 8 is a sectional view through two cooperating ends of adjacent corner sections, the view being on line 8-8 of Fig. 7

Fig. 9 is a similar-view on line 99 of Fig. 7; and v Fig. 10 are. perspective views of a loop or keeper at each end ofv several corner sections, illustrating the formation of the loop incooperation with. flanges of the remaining corner sections Wlll make sides of the frame as is apparent. Each of said flanges l6 and 17 is provided at itsouter termination with integrally formed strips 18 for the purpose hereinafter mentioned.

Referring to Fig. 1 the upright portions of corner sections 11 and 12 with their respective faces 15 and sides16, are positioned within the corresponding ends of corner sections 13 and L1 in the assembled state of the frame as is clearly apparent from Figs. 7, 8 and 9. This telescopic arrangement of said endspermits the upright extension of the frame. Asimilar arrangement is made for extension of the frame on horizontal line, wherethe horizontal ends of corner sections 11 and 13 are received within the corresponding ends of corner sections 12 and 1 1, so that the first mentioned ends are adapted for sliding movement within the latter ends.

To permit the reception of the upright ends of corner sectionsll and 12 within the corresponding ends of sections 13 and 14, and the horizontal ends of sections 11 and 13 avithin the cori'espondingends of sections '12 and 14 as hereinabove stated,the strlps 18 are maintained in the upright condition illustrated in the first position of Fig. 10. When all the ends of the corner sections are in a cooperative arrangement hereinabove mentioned strips 18 of both ends of corner sections 11. and 14 are bent horizontally toward the center of the frame, as illustrated in the second position of Fig. 10, thus direction from that shown on second position of Fig. 10 until position 20 of strips 18 shall abut the inner faces of the ends of corner sections 11 and 1 1 and shall terminate in a downwardly depending lip 21 abutting the inner faces of sides 16 and 17 of corner sections 11 and 1 1, all as illustrated on Fig. 8 and in the third position of Fig. 10.

From the hereinabove description it will be apparent that said strips 18 when bent will form loops wherein the ends of corner sections 12 and 13 will be adapted to make longitudinal sliding movement, horizontally and vertically, as the case may be.

Referring to Fig. 9 strips 18 of the corner sections 12 and 13 loop around the ends of sections 11 and 1e. l-lere, however, the strips 18 are bent in the reverse direction, the inner ends thereof abutting the inner faces of the ends of corner sections 11 and 1%, then passing over the upper faces 15 of sections 12 and 13 and then terminating in downwardly depending lips 22.

The interlocking arrangement and cooperation between the several corner sections is best illustrated on Fig. 7 which shows section 11 in operative engagement with the adjacent ends of sections 12 and 13. The relative position of section 1a in respect of the adjacent ends of sections 12 and 13 is similar to the relative position of the section 11 in respect of the adjacent ends of sections 12 and 13, both said sections 11 and 1 1 being covered at their ends by the adjacent ends of sections 12 and 13.

It is observed that by virtue of the fact: that the stripslS, or, in their ultimate for mation, the keepers, are integrally formed with each end of the several corner sections they maintain a symmetrical position relative to each other and to the frame no matter to what extent the frame may be adjusted. From the hereinabove description it will be further apparent that the frame may be reduced in size until the keepers 18 bear against the corner sections at their elbows, or extended until the two keepers on either two or four sides of the frame come to bear against each other.

The inner horizontal faces or keepers 18 are provided with rectangular supports 23 which are soldered or in any other suitable manner mounted upon each keeper, as shown on Figs. 2 and 3. The outer or rear walls of said supports have leaf springs 21 pivoted thereto by rivets 25. The opposite ends of said springs-curve downwardly and bear against picture and glass cover 26 preventing shifting thereof. The springs are adapted for swinging movement on their pivot points. To remove the picture from the frame springs 24 are swung around until they remain in parallel relation with the sides 16 of the frame, the frame is then extended and the picture will then be capable of ready removal.

A pair of opposite supports 23 on the corresponding sides of the frame is pro vided with an integrally formed lug 27, each having a downwardly projecting flange 28 provided with an aperture as seen on Figs. 2 and 3. Support illustrated on Figs. 4 and 5, by means of flanges 29 angularly projecting from legs 30 is adapted for pivotal mounting on flanges 28 of screws for the purpose of supporting the frame, as shown on Fig. 3. Said support is adapted for supporting the frame either horizontally or vertically, depending upon the nature of the picture, as is obvious, and for this purpose the frame is provided with two pairs of lugs 27 and flanges 28, one opposite pair thereof being on a line parallel to the horizontal axis of the frame and the other on the line parallel to the vertical axis thereof.

Each leg 30 of the support has a laterally projecting extension 31. The two extensions at their outer ends meet and are coupled by means of keepers 32 to provide an extensible brace for legs 30. Each of said keepers is in a rigid engagement with the end of its respective extension 31 and forms a slot for permitting insertion and sliding movement therewithin of the other extension. Thus the support is capable of extension on horizontal line with the extension of the frame on the same line.

While there is described herein a preferred embodiment of the present invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

What I claim as new is:

1. An extensible picture frame assembly comprising a plurality of sections formed L-shaped in cross-section and adapted to overlap in sliding contact with each other, and each of the respective ends of said sections having integrally formed thereon a lateral elongated strip adapted to be bent to engage about the free surface of the end of the section and the free surface of the adj acent overlapping section whereby to form a keeper to prevent relative disengagement of the sections.

2. Means for forming an extensible picture frame comprising a plurality of sections adapted to overlap in relative sliding contact with each other and each bent angu larly in cross-section to form the front and edge faces of the frame and the channeled picture receiving back, and each of the respective ends of each section having integrally formed thereon a lateral elongated strip adapted to be bent to engage about the free surfaces of the overlapping ends to form a keeper having a general cross-sectional configuration similar to that of the sections.

3. Means for forming an extensible picture frame assembly comprising a plurality of blanks each having an L-shaped body and a pair of strips extending laterally from the respective ends of the body, said body adapted to be bent to substantially define a rightangle in cross-section, and all of said bodies adapted to be placed together in overlapping relationship to form, a picture frame, the respective strips being bent in assembly to engage the free surfaces of adjacent portions of the overlapping bodies to provide keepers to hold said bodies in assembly.

' 4. A sheet metal construction for extensible picture frames comprising a plurality of L-shaped sheet metal bodies each having lateral end extensions and adapted to be bent to substantially define a right-angle in crosssection, and all of said bodies adapted to be placed together in overlapping relationship I to form a rectangular construction constituting the picture frame, the lateral end extensions adapted to be bent about and in engagement wlth the free surfaces of adjacent overlapping bodies to form keepers, and a support for the frame comprising sheet metal legs having lateral extensions the ends of which are provided with ears adapted to be bent to engage the adjacentifree surfaces of the extensions to form keepers whereby said support for the frame isrendered adjustable simultaneously with the frame and in the same operation.

In testimony whereof I aflix my signature.
